ag grinding wheel material removal rate

How to Determine Metal Removal Rates Themac

Removal Rate = Traverse (in./min.) x Depth (in.) x work diameter (in.) x 3.14. Example: Find the metal removal rate for an external grinding operation of 6" diameter shaft with a .001" depth of cut and a 12 in./min. traverse. Removal Rate = 12 x .001 x 6 x 3.14 = .023 in 3 / min. Traverse feed depends upon the width of the wheel being used and ...
